7 Claims. (CI. 45-77) This invention relates to extension drawer supports, and more particularly to a means of supporting a drawer in extended position, and which means is of such construction and is so mounted as to make it unnecessary to reduce the dimensions of the drawer to provide for the support, and likewise unnecessary to cut or form channels in the drawer or in the cabinet in which the drawer is mounted in order to accommodate the extension supports.

Many and diverse forms of drawer supports have heretofore been suggested for the use of supporting drawers in their extended position. These drawer supports have for the most part required the construction of the drawers or cabinets to provide for either (1) a reduction in the cubicle contents of the drawer, or (2) the cutting or forming of special channels or guides in either the drawer members themselves or in the cabinets or other members providing the uprights upon which the drawers are supported, making the cost of installation of such supports high for their utilization, requiring a reduction in the cubicle contents of the drawer.

It is an object of this invention to provide a drawer support for supporting a drawer in extended position, which support may be installed without forming special grooves or slots in either the drawer members or in the means providing the uprights upon which the drawers are supported, and which might be installed with a minimum of labor and without necessitating the reduction of the cubicle contents of the drawer in order to permit the utilization of the supports between the drawers and the uprights supporting the drawers.

Other objects and advantages of this invention it is believed will be apparent from the following detailed description of a preferred embodi- 40 ment thereof as illustrated in the accompanying drawings.

Fig. 10 is a horizontal section through the cabinet upon an enlarged scale, showing the drawer in its closed position, and partially broken away so as to illustrate more fully the extension means for the drawer.

Fig. 11 is a perspective upon an enlarged scale illustrating the extension means illustrated in Fig. 6, and representing the same removed from the cabinet.

In the preferred embodiment of my invention as illustrated in the accompanying drawings, there is illustrated a cabinet which may be of any suitable or desirable construction and which includes uprights or side walls I, cross members 261, and horizontally extending drawer slides 2, connected between the spaced uprights I and providing divisions in the cabinet in which the drawers 3 are mounted. The drawers 3 are of any suitable or desirable construction with plain fiat unobstructed outer side faces formed on the side walls or edge members 4, and having an elevated bottom 5, a rear member 6, and front boards 'I. The drawers 3 are of such width as to approximately fit the space provided between the horizontally spaced uprights I, leaving only a very slight clearance 8 between the edge members 4 and the uprights I.

The drawer support embodying my invention as illustrated in Figures 1 to 4', inclusive, includes a supporting member or slide preferably in the form of an angle member 9 formed of relatively thin gauge metal, of angular cross-section having a horizontal flange I0 and a vertical flange II. The relatively thin gauge metal or" the vertical flange I I consists of only one layer or thickness of the metal and fits'in the clearance 8 provided between the edge member 4 of the drawer 3 and the upright I, and this flange extends upwardly in the embodiment of my invention as illustrated in Figures 1 and 2 and the horizontal flange l rests upon the cross member 2 below the lower edge of the edge member 4.

As the metal used in forming the angle member 9 is of relatively thin gauge, and is the only part between the side of the drawer and the side wall of the cabinet, it can be fitted within the clearance normally provided in practically any drawer construction in any cabinet construction without necessitating the cutting away of any of the material forming the edge member 4, either at the point of clearance 8 or under the lower edge 12 of the drawer, but by reason of its angular crosssection it provides for suificient rigidity for an extension drawer support to support all loads normally carried in such drawers when the drawers are in their extended position as illustrated in Figure 1. The angle members 9 are formed to cooperate with relatively fixed means to limit their outward sliding movement and are preferably formed with slots l3 in the horizontal flanges l0, and fixed means such as a screw I4 is passed through the slots I3 and is secured in the guides 2 so as to permit the angle or support members 9 to slide back and forth with reference to the screws 14.

In order to provide stop members to prevent the drawer from being withdrawn too far from the cabinet or off from the support, the support 9 is provided with a limit stop I which is formed of the metal forming the flange Ill by bending the metal upward and at right angles to form the horizontally extended stop l5. Secured in proper position to the under edge of the edge member 4 of the drawer 3 is a clip 16 which is likewise formed to provide a horizontally extending limit stop I! which, when the drawer 3 is in extended position, will engage the limit stop IE to prevent accidental withdrawal of the drawer 3 from the cabinet.

Formed at a point near its rear, the slot I3 is enlarged as indicated at 18 to permit withdrawal of the support or angle member 9 with the drawer when the drawer is tilted upon being withdrawn from the cabinet. The enlargement [8 permits the head of the screw [4 to pass therethrough in withdrawing the support 9 from the cabinet. In order to provide for noiseless operation of the drawer, a small block IQ of rubber may be mounted upon a horizontally extending portion of either the stops IE or H, as desired.

In order to provide means for retracting the slides 9, a stop 20a is formed at the rear of each slide preferably by bending up a stout tongue of the metal at this point, and this tongue or stop 20a preferably carries a cushion of soft material such as a block 29 of rubber, fiber, or other suitable material. When the drawer is pushed back into the cabinet, the rear end of the drawer engages these blocks and retracts the slides.

It will be Observed from the foregoing that it is only required in the installing of the extension drawer support embodying my invention to mount the clip IB upon the lower edge of the edge member 4 and to properly position the screw l4 in the guide 2 of the drawer, and that this entire installation may be performed without cutting away any material portion of the wood forming the drawer structure or withoutreducing the volumetric contents of the drawer 3 and without cutting any grooves or slots or channels in either the uprights l or the edge members 4 of the drawers.

In order to provide the drawer support embodying my invention in a drawer structure for a cabinet which does not include the guides 2 or the transverse members 2a, a modified form of my invention as illustrated in Figures 5 and 6 is provided. In this structure similar parts have been indicated with similar numerals and the structure differs from that as heretofore described principally in that there is provided a second angle member 25a provided with a plurality of holes 26a through which screws 21a may be passed in securing the angle member 25a in. position upon the uprights la. Thus the second angle member 25a forms the guide and support upon which the member 9a is mounted. In this form of construction the support 9a is positioned upon the upper face of the angle member 25a with its edge within the channel 23a formed by bending a portion of the material of the angle member 25a upon itself, as indicated in Figure 5. In other respects the assembly is entirely the same as that heretofore described in connection with the modification of my invention as illustrated in Figures 1 to 4, inclusive. A clip like the clip l6 would be secured to the drawer in the same position as the clip H5 in Fig. 1.

In Figure '7 I have illustrated a runner stop adapted to be employ-ed when the runner slide 2 is of insufficient width to accommodate the screw [4. This runner clip 49 is secured to the frame member 2a by passing screws through the holes 4! and when so used acts in the same man- 'ner as does the angle support 25a illustrated in Figures 5 and 6.

Having fully described my invention, it is to be understood that I do not wish to be limited to the details herein set forth, but my invention is of the full scope of the appended claims.

I claim:
